Perhaps you should try some spelling variations:
"his educational supplement" » "his additional supplement", "his education supplementary", "his educational improvement", "gis educational supplement", "has educational supplement", "kids educational supplement"
"his occasional supplement" » "his additional supplement", "his occasional punishment", "his occasional retirement", "also occasional supplement", "_ occasional supplement", "few occasional supplement"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"his occasional supplement\") OR (\"his educational supplement\"))".
• Removing quotes may allow a broader search: (( his occasional supplement ) OR ( his educational supplement )).
• Adding a wildcard symbol may retrieve word variants: (("his occasional supplement") OR ("his educational supplement"))*.
